St. Louis is starting Tuesday like it slept in a sauna, with temperatures already climbing through the 80s and an afternoon high aimed at the low to mid 90s. Factor in the humidity and it could feel more like the low 100s later today, a setup that can turn outdoor work or exercise into a real health risk for older adults, young children and anyone without reliable air conditioning.
Heat Advisory Through This Evening
The National Weather Service has a Heat Advisory posted for the St. Louis metro through 7 p.m. Tuesday, warning that many neighborhoods could see a heat index of 100°F or higher. Forecasters say persistent northwest winds will help keep temperatures elevated and the air uncomfortably sticky well into the evening hours. NWS St. Louis
Cooling Centers and Safety Tips
For anyone who needs a break from the heat, the City of St. Louis is steering residents to public libraries and community centers that double as informal cooling sites during regular business hours. Call 2-1-1 for a complete list and to verify when each location is open. The city also provides help for seniors and people with disabilities, including assistance with AC installation and shelter options during periods of extreme heat. City of St. Louis
Relief Likely By Wednesday
A front sliding through tonight into Wednesday is expected to usher in drier air and lower humidity, with highs dropping into the upper 80s by Wednesday afternoon. That should break the worst of the stifling conditions, although forecasters still show a chance for scattered showers or thunderstorms later in the week. If you are planning outdoor events, aim for earlier or later in the day. Once the front moves through, afternoons should feel noticeably cooler and less muggy.
Quick Tips For Today
Drink plenty of water, skip heavy outdoor work during the hottest part of the day and keep an eye on elderly neighbors and pets. Never leave children or animals in a parked car, even for a short time. If someone starts showing signs of heat exhaustion or heat stroke, such as dizziness, confusion or loss of consciousness, seek medical help right away.
